Abstract

(T > 1200 °C)(T > 1200 °C)(T > 1200 °C)(T > 1200 °C)

The effect of neutron and gamma irradiation and magnetic fields on temperature sensors has been reviewed for the particular environment of the International Tokamak Experimental Reactor (ITER). Both Chromel–Alumel and Nicrosil–Nisil thermocouples are expected to be unaffected by neutron irradiation over the entire life time of ITER. Based on the available data, no significant radiation-induced electromotive force effects are to be expected. Magnetic field effects on Chromel–Alumel thermocouples could under certain conditions become important and, in this case, Nicrosil–Nisil thermocouples are recommended. For high temperature measurements (T > 1200 °C) in ITER conditions, tungsten–rhenium thermocouples are the most appropriate choice. Resistance thermometers, on the other hand, were found not to be usable in a reactor environment.
